Fan Spacer 4in w/ Bolts

The Jones Racing Products Fan Spacer 4in with Bolts (WP-9104-FS4) is a precision aluminum cooling system component engineered for engine bay applications requiring controlled fan mounting distances. Constructed from black anodized aluminum and supplied complete with all necessary hardware, this four-inch spacer delivers the exact offset depth needed to optimize radiator airflow and fan blade clearance in high-performance and custom engine builds where stock cooling geometry doesn't meet thermal demands.

The anodized aluminum construction provides corrosion resistance across engine operating temperatures and environmental exposure, critical for marine, off-road, and extended-duty applications. The black anodized finish resists oxidation while maintaining the professional appearance expected in show-quality and functional engine compartments. At 0.9 lbs, the spacer adds minimal weight while maintaining structural integrity under vibration and thermal cycling. Included bolts ensure compatibility right out of the box—no sourcing separate fasteners from multiple vendors.

This universal fan spacer serves engine builders, restoration specialists, and performance enthusiasts who require precision cooling system modifications. Whether relocating a mechanical fan for belt routing clearance, adjusting electric fan distance for shroud efficiency, or rebuilding a custom water-cooling loop, the four-inch spacing accommodates common OEM and aftermarket fan configurations. The spacer's dimensional stability under heat makes it suitable for both street and high-RPM track applications where thermal management directly impacts engine reliability and longevity.
